Application filed December 15, 1902. Serial No. 135,244.

To all whom it may concern:

Be it known that l, Vro'ron E. EDWARDS, a citizen of the United States, residing at Worcester, in the county of Worcester and Commonwealth of Massachusetts, have invented a new and useful Improvement in Twist-Delivery Guides for, Rolling-Mills, of which the following is a specification accompanied by drawings, forming a part of the same, in'which-'- Figure 1 is a front elevation of a roll housair of rolls with one of my im- Fig. 2- is a vertical sectional view on line 2-2 Fig. 1.

guide detached roin the-roll housing. Fig.

showing the position of the bar as it enters the guide, and Fig. 7 is an end view of the delivery end of the guide with a bar between the guide plates, showing its position as it leaves the guide. 1.

Similar referenceletters and figures refer to similar parts in the different views. -f

The object of my present invention 1s to provide means for. regulating with precision the initial twist to be given a'metal-bar as it is delivered from one set of rolls, in order" to impart a predetermined degree of twist to. the bar by the time it arrives at the next suc.-'

needing set-of rolls; and this isflbrought about by passing the bar through a guide com rising a pair of guide plates capable. of adjust" ment to give the required initial angular torsion to deliver the bar to the next set of rplls:

in the exact position to enter their grooves.

Referring to the'accompanying drawings,

A denotes a roll housing, and B, C, apair of rolls having grooves D and E and provided with one of my twist delivery guides in which 1 denotes a base plate secured upon a bracket 2 by a bolt 3 and capable of vertical adjustment to bring the guide to the required elevation relativeto the rolls B and C. i

Erected at opposite edges of th base plate and preferably integral therewith are the sides 4 and 5. A pair of guide plates 6- and' 7 are held between the vertical sides 4. and 5 and supported u 'onthe-base plate 1 so as to bring thespace b etween their opposing s'ur-" faces in position to receive a bar'as it issues.

frombetween said rolls. The lower guide plate 6 rests upon the base plate 1, and is provided upon opposite edges with projecting cheeks 8, 8 and 9, 9., which contact with the sides 4 and 5 and hold the guide plate from lateral movement. Arms 10, 10 and 11, 11 project laterally from the opposite edges ofthe lower guide plate and overlap the front and rear edges of the sides 4 and 5 to hold the plate from 1011 itudinal movement and provide seats'for t e vertically adjusting screws of the upper guide plate 7. The upper guide plate 7 has arms 12, 12 and 13, 13 which overlap the sides 4 and 5 and hold the plate from longitudinal movement, and it is also provided with cheeks 14, 14 near its forward end which contact with the sides 4 and 5, and

plate from lateral movement, while the rear,

.end is capable of sidewise adjustment by means of horizontally adjusting screws.

The upper plate 7 is verticallyadjusted by screws 15, which pass through holes in the arms 12, 12 and 13, 13 and have their lower ends seated on the arms 10, 10 and 11, 11 of the lower guide plate, and carry nuts 16 which are screwed up or down-and serve to support the upper guide plate. The rear end of the. upper guide plate 7 is adjusted sidewise by the screws 17, 'l7 which are screwed into the sides 4 afnd'5 and bear against the edges/of the guide plate 7.

The. sides 4-and5have across bar' 18, in which is held a clamping screw 19, bearing a ainst the upper surface of the upper guide p ate to hold it in contact with the nuts 16.

The'g'-uide plates 6 and 7 maydiave the opposing surfaces plainto suit thegsidesof a flat bar, or they may be grooved, as in the present instance 'bygrooves 20 and 21, adapted to receive a lozengeshaped bar in cross section as shown at 22'. The grooves 20 and21, are adapted to receivea lozenge shaped bar 22, as it isdeliver ed from thepair of rolls B, C with its: longest diameter, as ,indio'atedby thebr oken line a, tn-lying in a horizontal plane and the upper and lowerg'uide plates 6 and 7 are arranged to bear against opposite edges and upon opposite sides of the bar,

while the center of the grooves are 'sufliciently cut. away to afford clearance for the intermediate, angles of the-bar;

I The surfaces-ofthe guide plates contacting with a bar passin between them is slightly warped or twiste ,so as toimpart an initial hold the forward end of the upper guide 1 the amount of initial twist serted adapted to bars twist to the bar in its passage through the i guide plates.

The present guide plates 6 and 7 are provided with longitudinal grooves 20 and 21, and

bear a ainst the acute an led corners of the lozen e shaped bar lie in planes which are 'slightlytwisted sons to impel-tan initial twist to the bar. in Fig. 6. he oosition of the bar 22 is shb= n as it enters liveen the guide plates, wilh longest diameter in'a horizontal plane, as shown by the broken line a, a, but the Y ped or twisted so th at in its passage through the guide plates one edge of the bar is tipped shown in 7, and indicated by the iii'clination of the broken line b, b, to a horizontal plane. This tipping of the bearing surfaces of the plates gives an initial twist to the bar, as shown in Figs. 5 and 7, and causes a varying degree of pressure to be imparted to the edges of the bar, corresponding to the force required to twist the bar.

The amount of initial torsion or twist thereby given to the bar, by its passage through the guide, is suflieient to rotate the bar a one quarter turn by the time the bar reaches the next succeeding pair of rolls, and can be varied by the adjustment of the upper guide plate 7. The vertical adjustment f the upper guide plate is accon'iplished by raising or lmvering the nuts 16 on the screws 15, and the horizontal adjustment is brought about by the screws 17, 17, held in the sides 4- and 5.

The base plate 1, with its sides 4 and 5, form a supporting frame i'orthe guide plates 6 and 7, the lower of which is removably held in the frame, but stationary by means of the contact of its checks 8 and 9, and its arms l0 and 11, which engage the sides l and 5. The upper guide plate is also removable from the frame and is held at the proper distance from the lower plate by the screws l5 and nuts 16. l

The upper guide plate is held in position by "the clamping screw 19, held in a removable cross bar 18, whose opposite ends pass under the projecting lips i and 5. By loosening the clamping screw 15),the cross bar 18 and the guide plates 6 and 7 are all easily removed, allowing other guide plates to be inof di'll'eront shapes and sizes.

What 1 claim as my invention and desire to secure by Letters Patent 1s1- 1. A delivery guide fol-rolling mills, com prising a pair of guide plates adapted to receive a bar between them with the opposing surfaces of said guide plates .win'ped or twisted and arranged to bear with varying degrees of pressure against the opposite edges of the bar, thereby imparting a torsionalmovement to the bar as it passes be tween saidplates, and means for adjustably regulating the amount of clearance between the edges of the grooves which plane of the edges of the grooves are shghlly war seams j said plates, whereb f the dilicrence in the do- 1 greeol pressure imparted to the dill'crent sides 01' .iar may be varied.
